Why convert JP2 to WEBP?
Introduced in 2000 by JPEG Committee, JP2 was great for its time. But WEBP (created in 2010 by Google) offers lossy/lossless compression and 24-bit – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
